Yes, that's correct (2.1.9 actually) but do mind SR7 timezone (I think he lives somewhere in the US Midwest, not sure). Considering past updates release times I'd say we are still more than 24h away of the release of 2.1.9 , however last update did came a couple hours earlier than usual so you never know.
Beware of trolling from the patreons, they like spreading misinformation to troll non-patreons, so don't believe anything that doesn't come out from either the official patreon page or the annoucement channel in the official discord (And only that channel).
I'm quite excited for this update, it's easy to see that the developers are quite confident on it, despite the previous update being quite hard to uphold.
Also just realized a possible motive for them choosing Miss Martian for 2.2, that update is from the months of December and January, the holidays, which means that SR7 (Not a Porn drawing machine) will take a few days off to chill. And since Miss Martian is already decently progressed all around it won't take much effort to at least deliver all of her remaning content. (Exhibition and the rest of cell stuff.)
The Artemis update after that is also shaping up to be something(heh) quite interesting because it also means Chesire gets some content and who doesn't like some SisXSis content. I do wonder who will be the heroines that are going to be choosen after the ones we already know, if I got to choose it would be Batgirl, Supergirl and Wonder Woman.
Either way the future looks bright for this game and I'm satisfied.
